We studied the electrical performance of ambipolar organic transistors based on an F16CuPc/α6T pn heterojunction illuminated by a light from a white LED. As the illumination intensity is increased up to ca. 3000 Lux, the hole mobility decreases to about 1/3 while the electron mobility is only slightly increased. Photogeneration carriers (electrons) enhances n-channel operating characteristics, which...
The electrical performance of the F16CuPc/α6T TFT was also studied, illuminated by a visible light from a white LED and the performance of the device as a phototransistor. As the illumination intensity is increased from 0 to 3.0 k Lux, the hole mobility decreases to about 1/3, while the electron mobility is only slightly increased. The mechanism of light enhanced photocurrent of n-channel is based...
